The height of an object can be represented as a function of time.
It takes the rocket 25 seconds to hit the ground
The height function is given as:
![\mathbf{h(t) = 400t - 16t^2}](https://tex.z-dn.net/?f=%5Cmathbf%7Bh%28t%29%20%3D%20400t%20-%2016t%5E2%7D)
When the rocket hits the ground, we have:
h(t) = 0
So, the height function becomes
![\mathbf{ 400t - 16t^2 = 0}](https://tex.z-dn.net/?f=%5Cmathbf%7B%20400t%20-%2016t%5E2%20%3D%200%7D)
Rewrite as:
![\mathbf{ 16t^2 = 400t}](https://tex.z-dn.net/?f=%5Cmathbf%7B%2016t%5E2%20%3D%20400t%7D)
Divide both sides by 16t
![\mathbf{ t = 25}](https://tex.z-dn.net/?f=%5Cmathbf%7B%20t%20%3D%2025%7D)
Hence, it takes the rocket 25 seconds to hit the ground
